FM 17-42 Armored Infantry Battalion 1944-11-10
"This manual covers the tactical employment of the armored infantry battalion, both as part of a larger force, and when acting independently. It is designed as a guide and does not prescribe a set of inflexible rules. Each tactical situation must be solved on its own merits and the initiative of individual commanders is encouraged."
